What is claimed as new is:

1. In a motor, the combination of an upright spindle, a ed thereon and adapted for connection to a transmission device, and two prcipellers on the shaft, one having its blades standing at an angle and manually adjustable, and the other having Iits blades automatically adjusted by a speed-regulated governor.

E2. In a motor, the combination of an upright spindle, a tubular shaft mounted thereon, and adapted for connection to a driven member, two propellers whose hubs are rigidly mounted on said shaft, the lblades of one propeller having pins frictionally engaging its hub and manually adjusted as to their angles, the blades of the other propellerhaving pins at their inner ends piv tubular drive shaft mountotally engaging its hub, cranks on these blades also at their inner ends, and a speedregulated governor mounted on said shaft vand connected by links with said cranks.

In testimony whereof I aiilx my signature in presence of two witnesses.
